long stroke balancers tool balancers spring balancers zero gravity balancers tool balancer
ENDO Long Stroke Spring Balancers are designed for high ceiling applications. They provide true "zero gravity"
tool holding with no drifting or strain. The tapered drums and quality springs and bearings provides smooth cable
travel throughout the stroke. Tension adjustment is easy and precise. The ELF models offer both the automatic brake
and the manual drum safety lock. In the event that a spring breaks, an automatic centrifugal brake engages and locks,
preventing damage to the tool. With the manual lock engaged, the drum will not rotate. This allows for easy change
out or maintenance of tools. Choose the correct balancer based on the total weight to be balanced (tool and all
accessories) and stroke requirements. Try to utilize the upper range of the balancer capacity ratings.
ELF Series Balancers Feature
• Cast aluminum case and a forged swivel hook.
• Automatic Safety Brake
• Manual Drum Safety Lock
• Exclusive 18 month warranty.

Features and Benefits
ENDO Spring Balancers are a valuable addition to your
assembly line. They support heavy tools with cable tension
equal to the weight of the suspended tools, which makes
them seem virtually "weightless". As the tool is repositioned
the balancer extends or retracts the support cable to follow
the tool's movements. Constant tension on the cable is
accomplished with a spring motor and a tapered drum. The
assembler has the flexibility to reposition the tool, while
experiencing comfortable operation and less fatigue. Similar
to a Balancer is the Retractor, which does not have a
tapered drum. The tension on the cable increases as the
cable is extended

Advantages of Using an ENDO Spring Balancer:
• Suspend tools in assembly lines or other work areas
• Help the assembler with repetitive tasks such as
   installing fasteners: screws, nuts, bolts, etc.
• Hold fixtures, tools, welding guns, and similar
• Improves efficiency and diminishes worker fatigue
• Stabilizes tool positioning and contributes to work
• Contributes to a safer working environment
• Keeps fixtures, tools, and welding guns off of the floor
   and clean.
• Eliminates the need to separately power the balancer

Application Guidelines
• Size the balancer to carry the total weight to be balanced - tool plus all accessories - and stroke (maximum to
   minimum height) required.
• Size to the upper end of the capacity range of the balancer when possible.
• Always attach secondary support cable(s) to the eyelet provided for additional safety.
• Balancers are normally hung vertically and the rope is pulled out vertically. To prevent the rope from wearing on the
   guide, the rope should not be pulled out at an angle to the balancer body. The balancer can also be mounted
   horizontally, however a pulley system must be employed to guide the rope straight out of the balancer then down to
   the tool. Again, care must be taken to prevent the rope from wearing on the guide. A trolley and rail system can be
   used to help the balancer adjust to changing angles.
• If multiple balancers are used in close together, install them at staggered heights to keep them from hitting each other
• The spring tension is factory preset to the mid-range of the rated capacity. To adjust the tension turn the worm gear
   or spindle clockwise to increase the tension and counterclockwise to decrease the tension.
